How to change the location of tns_admin in Oracle 11gr2?

In DOS prompt, I setup TNS_ADMIN (For example, set TNS_ADMIN=D:\ ) to point to a location, saying D:\ since I have the customized tnsnames.ora and sqlnet.ora files there. However when I tnsping dbname in the same DOS window, it shows that sqlnet.ora still uses the default one: $ORACLE_HOME/network/admin. Is there anyway to let tnsping use the customized one in D:\ ? I greatly appreciate it if any gurus can shed some light on it.

>>Set TNSADMIN as a system environment variable.

It can be a local variable for testing as shown above.

Granted, it should be a system variable once you get everything set up the way you want it.

Doing a little more experimenting:
It looks like tnsping looks in the current folder first.  So if you were sitting in $ORACLE_HOME/network/admin when you ran it, it will use the one found in there and ignore the TNS_ADMIN variable.
